Abstract
A panel construction including one or more pultruded box beams disposed between first and second outer sheets at selected locations. A core or filler material may also be disposed between the first and second outer sheets at selected locations. For example, the core material may be disposed between the first and second outer sheets and fill in the space between the box beams. In another example, the core material may include channels or recesses and the box beams may be positioned in the channels or recesses in the core material.
Claims20
A modular structural panel, comprising:
- a pultruded box beam having a first side and a second side forming an integrated structural frame of the modular structural panel, the pultruded box beam being a weight-bearing beam comprised of a combination of fiberglass and thermosetting resin;
- a first outer sheet coupled to the first side of the integrated structural frame;
- a second outer sheet coupled to the second side of the integrated structural frame;
- and
- a high-density foam interposed between the first outer sheet and the second outer sheet adjacent to the pultruded box beam.
A modular structural panel, comprising:
- a first outer sheet;
- at least one horizontal pultrusion coupled to the first outer sheet;
- at least one vertical pultrusion coupled to the first outer sheet, the at least one horizontal pultrusion and the at least one vertical pultrusion forming an integrated structural frame of the modular structural panel;
- a core material coupled to the first outer sheet, the core material adjacent the at least one horizontal pultrusion and the at least one vertical pultrusion, the at least one horizontal pultrusion and the at least one vertical pultrusion each being a weight-bearing structure comprised of a combination of fiberglass and thermosetting resin;
- and
- a second outer sheet coupled to surfaces of the at least one horizontal pultrusion, the at least one vertical pultrusion, and the core material distal from the first outer sheet.
A modular structured panel, comprising:
- a first outer sheet and a second outer sheet corresponding with the first outer sheet;
- a plurality of pultrusions interposed between the first and second outer sheets, the plurality of pultrusions including first pultrusions oriented in a first direction and second pultrusions oriented orthogonally with respect to the first pultrusions, the first and second pultrusions being bonded to the first and second outer sheets and forming an integrated structural frame of the modular structural panel, each pultrusion of the plurality of pultrusions being a weight-bearing structure comprised of a combination of fiberglass and thermosetting resin;
- and
- a core material interposed between the first and second outer sheets and adjacent to the first and second pultrusions;
- the core material being bonded to the first and second outer sheets and first and second pultrusions.
